The COVID-19 pandemic has had a tremendous influence on global health. Over 50 million people were exposed to the virus in 2020, and over 1.5 million died as a result of respiratory problems.

According to research, properly wearing a mask and constantly adopting excellent social distance can considerably prevent the spread of the coronavirus (COVID-19).

However, concerns about probable aerosol transmission have prompted many people to choose air purifiers. So, how do different kinds of air purifiers work? Do any of them work against COVID-19? Should you get one for your home?

Let us look at how you can help protect yourself from the deadly Coronavirus with an air purifier along with following the basic precautions and guidelines.

What is Covid-19?

Coronaviruses are a type of virus that can cause respiratory disease in humans.

The name “corona” comes from the virus’s many crown-like spikes on its surface.

Coronavirus causes sickness in humans including severe acute respiratory syndrome (SARS), the Middle East respiratory syndrome (MERS), and the common cold.

COVID-19, a novel coronavirus strain, was initially identified in December 2019 in Wuhan, China. Since then, the virus has spread to all continents (except Antarctica).

4,987,910 people have died so far from the coronavirus COVID-19 outbreak as of October 28, 2021. This virus has destroyed the whole world mechanism by isolating people from the outer world.

The whole world order has changed since the pandemic hit. Retail stores and shopping stores have turned to e-commerce stores. Schools have transformed to zoom sessions. Office jobs have transformed and given rise to a work-from-home culture.

Organizations busy in the collection of this information, including the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC), are gathering information and continually refining their understanding of how this deadly virus spreads through scientific and medical studies.

How exactly does Covid-19 spread?

COVID-19 is a dangerous infection that is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). When the virus comes into touch with mucous membranes, such as those in the eyes, nose, and mouth, it can cause disease and even death.

COVID-19, like measles and influenza, is a viral infection that can be spread via aerosol transmission.

It can, however, be spread by other common means like:

  • When an infected person coughs, sneezes, talks, sings, or breathes near you, the virus spreads in respiratory droplets (within six feet). This is assumed to be the primary method by which COVID-19 is propagated.
  • When the virus spreads in small respiratory droplets that linger in the air for minutes to hours from an infected person who is more than six feet distant or has already left the area. This mode of transmission is more likely to occur in enclosed environments with insufficient ventilation.
  • Close contact (touching, shaking hands) with an infected individual.
  • By touching virus-infected surfaces, then touching your eyes, mouth, or nose before washing your hands.

Governments, health organizations, researchers, and healthcare practitioners are all collaborating to devise policies and practices that will prevent the transmission of this virus both internationally and from person to person.

Mechanical air purifiers use mesh filters, which are commonly made of glass or specific synthetic fibers, to catch pollutants.

Mechanical air purification filters include High-Efficiency Particulate Air (HEPA) and HyperHEPA filters.

Mechanical filtration is the most effective and safest way of removing airborne particles from the air.

Air purifiers, when used appropriately, can help minimize airborne pollutants such as viruses in a house or confined environment.

A portable air cleaner, on the other hand, is insufficient to protect humans from COVID-19.

Using an air cleaner in combination with other practices recommended by the doctors and government can be part of a plan to protect yourself and your family.

An air cleaner must be able to remove airborne particles in order to be efficient at removing viruses from the air (in the size range of 0.1-1 um).

Manufacturers use High-Efficiency Particulate Air (HEPA) filters in order to provide Air Purifier for Covid.

HEPA filter against Covid

HEPA (high-efficiency particulate air) filters are an air filter efficiency standard. They are also known as high-efficiency particle absorption filters and high-efficiency particulate arrestance filters.

Filters that fulfill the HEPA standard must meet specified efficiency requirements.

Common regulations demand that a HEPA air filter remove at least 99.95 percent of particles with sizes equal to 0.3 m from the air that passes through it, with filtration efficiency rising for particle diameters less than and greater than 0.3 m.

Pollen, filth, dust, moisture, germs, viruses, and submicron liquid aerosol are all captured by HEPA filters.

To extend the life of the more expensive HEPA filter, a HEPA bag filter can be used in conjunction with a pre-filter (typically carbon-activated).

In such a configuration, the first stage of the filtration process consists of a pre-filter that removes the majority of the bigger dust, hair, PM10, and pollen particles from the air.

The finer particles that escape from the pre-filter are removed by the second stage high-quality HEPA filter.

This is a regular occurrence in air-handling devices.

Conclusion:

Many guidelines have been published on how to create a clean and healthy environment post covid. But is there any post-covid world?

What should be kept in mind though, is that as easy as it sounds, air purifiers should not be used as the first line of defense against viruses. The first lines of defense should be social separation, masking, and excellent cleanliness.

However, an air purifier by a good company with HEPA- filter can filter airborne ultrafine particles, including viruses like COVID-19, which is an important aspect of a virus-prevention strategy. Using a Co2 Monitor in correspondence to that can help you keep your indoor air clean.

Viruses can be collected by filters intended for microscopic particles, but this does not ensure complete protection – airborne transmission is only one method viruses propagate.

Even the most effective air filters are not completely effective in stopping the deadly virus.

So stay safe at your home. Ensure healthy living by adopting the safety guidelines by health officials
